Detailed Description

Describes a Command Stream.

A N3D command stream can contain commands to set positions, normals and texture coordinates. The commands being transfered to the Geometry Engine using direct memory access. Due to the direct memory access transfer, the data cache must be flushed prior the call to N3DDEVICE::DrawPrimitive and a command stream cannot be located in the DTCM region (e.g. stack) as the DTCM is not connected to the DMA bus.
